GRAIN-DRILL.

'PECIFICATION forming part cf Letters Patent No. 720,720, dated. February 17, 1903. Application filed June 10, 1902. Serial No. 111,060. (No model.)

To all zuhmn it may concern:

Be it known that I, FRANK E. MARSH, a resident of La Crosse, in the county of La Crosse and State of Wisconsin, have invented certain new and useful Improvements in Grain- Drills; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in grain-drills, the object of the invention being to provide an improved mounting for the disk furrow-opener and grain-feeding boot, so as to deposit the grain in the ground without obstruction and maintain the disk comparatively clean, preventing any accumulation of dirt from interference with the grainfeed.

With this object in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figures 1 and 2 are views of opposite sides of my improvements. Fig. 3 is a view in horizontal section, and Fig. 4 is a view illustrating a modification.

1 represents a grain-dropping boot provided being disposed adjacent to the arm 2 and boot 1, and a scraper 5 is secured to the boot 1 near its upper end and bears against the concave face of the disk to clean the same.

A beveled or sharpened scraper-bar 7 is secured at one end to the hub of arm 2 and at its opposite end by bolt, screw, rivet, or otherwise to thetoe of boot 1 and extends diagonally across the convex face of disk 6 to effectually clean the latter and prevent any dirt from passing into the space between the scraper 7, arm 2, and boot, which space I have designated 8. This open space Sis therefore always maintained free from dirt, so that,

if desired, I might cut away the face of boot 1 adjacent to the convex face of disk 6, as shown in Fig. 4, and permit the grain to fall against the face of disk 7 before dropping into the ground.

It will thus be seen that with my improvements the boot 1, arm 2," and scraper '7 are all located entirely upon the convex or side face of the disk and out of the wayof the furrow turned by the disk. 7

Various slight changes might be made in the general form and arrangement of parts described without departing from the spirit and scope of my invention, and hence I do not Wish to be limited to the precise details set 'forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope thereof.

Having fully described my invention, what I claim as new, and desire to secure byLettcrs Patent, is-

1. The combination with a c oncavo-convex disk, of a boot-,an arm on the boot forming the hub to support thedisk, and a scraper connecting the toe of the boot and the hub, all located on the convex side of the disk.

2. The combination with a concave-convex disk, of a boot located adjacent to the convex'face of said disk, an arm on said boot comprising a hub for the disk and located adjacent to the convex face of the disk, and a scraper connecting the hub and toe of the boot and leaving an open space between said arm, boot, and scraper.

3. The combination with a concavo-convex disk, of a boot, an arm provided with a hearing for the disk, a scraper connecting the arm and toe of the boot, said arm, boot and scraper 'all located on the convex side of the disk,

and a second scraper secured at its upper end directlyto the boot and terminating at its lower end against the concave face of the disk. In testimony whereof I have signed this specification in the presence of two subscribing witnesses. 1
